Why Video Specs Matter

Videos that exceed file size limits or use unsupported formats may fail to upload or be heavily compressed. Incorrect aspect ratios can lead to distracting cropping or black bars. When your videos play smoothly with clear audio and sharp visuals, you reinforce your professional brand and encourage higher engagement.

Video File Formats & Size Limits

LinkedIn supports common video formats, but MP4 remains the industry standard for optimal performance. MOV files are accepted, but may not compress as efficiently.

• Native posts: Up to 5 GB per video
• Video ads: Up to 500 MB officially, though under 200 MB is advised
• Minimum size: 75 KB - videos below this will not process

Staying well under the maximum size ensures quicker uploads and smooth playback, even on slower connections.

Video Duration

LinkedIn allows videos as short as 3 seconds and up to 10 minutes for organic posts. For paid ads, the maximum extends to 30 minutes.

• Minimum: 3 seconds (desktop), 2 seconds (mobile)
• Maximum: 10 minutes for native posts, 30 minutes for ads

Despite the broad limits, engagement often peaks for videos under one minute. For most professional updates, aim for 30 to 90 seconds to maintain viewer attention and deliver a clear message.

Safe Zones & Text Overlay

LinkedIn overlays UI elements like profile images and buttons on your video.

• Keep vital text and visuals within the central 86% of the frame
• Avoid the top and bottom 7% margins

Position captions, logos, and CTAs away from edges to avoid obstruction.

Native vs Shared Videos

Native video uploads on LinkedIn autoplay and get better reach. Shared links like YouTube embeds do not autoplay and often have lower click rates.

• Native video: Autoplay, higher visibility, better completion rates
• Shared links: Static previews, lower engagement

Always upload videos natively for best performance.

Best Practices for High-Performance Videos

• Hook in the First 3 Seconds: Start with a strong visual or question to reduce scroll-past rates.
• Use Captions: Ensure your message is understood during mute autoplay and aid accessibility.
• Optimize for Mobile: Over 60% of views are on mobile; use bold visuals and concise overlays.
• Include Clear CTAs: Guide viewers on next steps with prompts like “Comment Below” or “Learn More.”
• Leverage Analytics: Track completion rates, demographics, and view counts to refine your strategy.
• Experiment with Ratios: Rotate between 16:9, 1:1, and 4:5 to identify top performers.
